The vertical shaft and the cross channel are the important part of the tunnel project, which belongs to the complex underground space structure. The change of stress and strain state of soil around. The vertical shaft and cross channel has space effect. According to the theory of the Mohr-Coulomb constitutive theory, the 3D numerical simulation of the vertical shaft and the cross channel is carried out by using the finite element analysis software MIDAS/GTS. Calculation results are basically consistent with the field monitoring data, proved the...
